CVE-2025-24973
CriticalSummary
Concorde, wcześniej znany jako Nexkey, to fork federacyjnej platformy mikroblogowej Misskey. Przed wersją 12.25Q1.1, z powodu niewłaściwej implementacji procesu wylogowywania, dane uwierzytelniające pozostają w ciasteczkach nawet po wylogowaniu, co może umożliwić atakującemu kradzież tokenów uwierzytelniających.
Risk Assessment
Może to mieć katastrofalne konsekwencje, jeśli użytkownik z uprawnieniami administratora korzystał z urządzenia współdzielonego. Użytkownicy, którzy logowali się na współdzielonym urządzeniu, są narażeni na kradzież swoich danych uwierzytelniających.
Recommendation
Zaleca się, aby użytkownicy, którzy korzystali z współdzielonych urządzeń, przeszli do Ustawienia > Bezpieczeństwo i wygenerowali nowe tokeny logowania. Wersja 12.25Q1.1 rozwiązuje ten problem, a jako tymczasowe rozwiązanie należy wyczyścić ciasteczka i dane witryny w przeglądarce po wylogowaniu.

The 10Web Booster – Website speed optimization, Cache & Page Speed optimizer plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 2.34.10 via the compressCustom function. Missing file type validation and extension filtering on the page_id parameter, combined with a world-readable leaked nonce that bypasses authentication checks, makes it possible for unauthenticated attackers to upload files that may be executable, leading to remote code execution.
- CVE-2026-93483Critical
In Znuny through 7.3.6, an attacker can bypass specific standard login procedures and gain unauthorized access to sensitive system functions by manipulating a specific HTTP request header. Because the application incorrectly trusts this header, an attacker can impersonate any user, including administrators, without requiring a password. The HTTPBasicAuth modules for the agent and customer interfaces read the username not only from $ENV{REMOTE_USER} but also, as a fallback, from $ENV{HTTP_REMOTE_USER}, which is populated directly from an attacker-controllable "Remote-User" request header.
- CVE-2026-110911Critical
Wheels 1.1.8 through 4.1.1 allows SQL injection when caller-supplied quoted values are parsed again as SQL by dynamic finders (such as findOneByEmail), the query builder's where(property, value) and where(property, operator, value), string/UUID-key lookup paths (findByKey, updateByKey, deleteByKey and findOrCreateBy...), and validatesUniquenessOf. The parser incorrectly treats a doubled single quote as the end of a literal. Applications passing request data to these APIs can expose authentication, password-reset or token lookups, and data to unauthorized access; numeric-column values are not affected.
- CVE-2026-110862Critical
Better Auth from 1.4.0-beta.18 before 1.7.7 contains an authentication bypass vulnerability that allows unauthenticated attackers to sign in as other users by reusing OAuth state values as Magic Link tokens. Attackers can start an OAuth sign-in with a victim's email and submit the returned state to Magic Link verification, gaining sessions or creating falsely email-verified accounts.
- CVE-2026-108336Critical
When the default self-signed certificate is used, an attacker could gain administrative access to the application. The SSL certificate for the web interface is used to sign JWT access tokens that validate that the user is logged in; with the default certificate, an attacker could sign JWT access tokens and bypass login. An attacker could gain administrative access and perform actions like configuring the service or requesting log collection; device credentials and customer data cannot be accessed with this vulnerability.
- CVE-2026-108335Critical
When the password reset functionality is enabled, and email is configured, an attacker could take over any account using a brute-force attack. There is no rate limiting on the attempts to enter the reset code, leading to the possibility of a brute force solution to the password reset challenge. An attacker could gain administrative access to the application and perform actions like configuring the service or requesting log collection; device credentials and customer data cannot be accessed with this vulnerability.
- CVE-2026-55684Critical
In WeGIA prior to 3.8.6, the unauthenticated cadastro_cobrancas_geracao.php endpoint accepts POST data via extract($_REQUEST) and inserts it directly into an INSERT statement. Numeric parameters are unquoted and unvalidated, while string parameters can break out of their SQL context. A remote attacker can execute arbitrary SQL to read or modify billing, member, employee, permission, and credential data, or delete database tables.
- CVE-2026-55683Critical
In WeGIA prior to 3.8.6, the unauthenticated cadastro_cobranca.php endpoint accepts POST input via extract($_REQUEST) and directly incorporates valor, valor_pago, id_pessoa, id_socio, and id_sociotipo into UPDATE, INSERT, and SELECT statements without prepared statements. A remote attacker can execute arbitrary SQL to read or modify WeGIA database content, including billing records and credential data. The same SQL access can delete or truncate tables, causing loss of application data.
- CVE-2026-55680Critical
In WeGIA prior to 3.8.6, unauthenticated POST requests to web/html/socio/sistema/cadastro_cobranca.php can place a quoted SQL expression in the codigo parameter, which extract($_REQUEST) passes into the WHERE codigo= clause of an UPDATE statement without validation or parameter binding. Quoting the value bypasses MariaDB type conversion for the VARCHAR column and permits arbitrary SQL execution without a session. An attacker can read or modify database content, including user credential hashes and billing records in the cobrancas table.
- CVE-2026-85714Critical
In Stirling-PDF prior to 2.13.2, an authenticated administrator using the default H2 database and security mode can upload a crafted SQL file to POST /api/v1/database/import-database. DatabaseService.validateSqlContent() splits normalized input on semicolons and accepts a statement when it contains any allowed keyword, allowing dangerous H2 functions such as FILE_READ and CSVWRITE, plus CREATE ALIAS, to bypass the insufficient whitelist and execute side effects when RUNSCRIPT processes the file. This permits arbitrary file access. The demonstrated operating-system command execution chain writes attacker-controlled startup files to a user-site location and then triggers an application Python interpreter configured to load those startup files, resulting in command execution as the JVM service account.
Original NVD description (English source)
Concorde, formerly know as Nexkey, is a fork of the federated microblogging platform Misskey. Prior to version 12.25Q1.1, due to an improper implementation of the logout process, authentication credentials remain in cookies even after a user has explicitly logged out, which may allow an attacker to steal authentication tokens. This could have devastating consequences if a user with admin privileges is (or was) using a shared device. Users who have logged in on a shared device should go to Settings > Security and regenerate their login tokens. Version 12.25Q1.1 fixes the issue. As a workaround, clear cookies and site data in the browser after logging out.
